iamf-sentinel-mcp

An MCP server exposing iamf-sentinel (IAMF conformance validator) and iamf-loom (IAMF packager) to MCP clients — Claude Desktop, Claude Code, and any other agent runtime that speaks the protocol.

IAMF is the Alliance for Open Media's Immersive Audio Model and Formats (v1.1.0). This server lets an agent validate IAMF files against the spec's conformance rules and compile packaging manifests into inspectable, deterministic plans — without executing anything (execution is a separate, per-launch opt-in — see below).

Code comments throughout cite an internal numbered design docset (doc NN), ADRs, and pre-registered expectation labels — DESIGN-NOTES.md explains the notation and indexes every cited document.

Tools

Resources

• checks://catalog — every S-code check the validator can emit: severity, layer, title, description, related F-register entries.
• mcodes://catalog — every M-code compile diagnostic the packager can report, with its stable summary (retired codes kept for the record).
• fregister://catalog — the failure-mode register (F_TO_CHECK.md): the WP1/WP3 failure catalogue mapped to Sentinel checks, as markdown.

Run

pip install iamf-sentinel-mcp
iamf-sentinel-mcp                # stdio transport, read-only (default)
iamf-sentinel-mcp --enable-run   # additionally registers loom_run (executes)

Claude Desktop / Code config:

{ "mcpServers": { "iamf-sentinel-mcp": { "command": "iamf-sentinel-mcp" } } }

Scope and posture

• Read-only by default. Without --enable-run, tools parse and compile; nothing is executed, no files are written, no network is touched.
• Execution is opt-in, per launch. --enable-run registers loom_run, which runs the encoder toolchain as subprocesses and writes files; the Sentinel gate inside loom run stays on by default. A missing toolchain is an actionable error naming the expected binary path. Sentinel L3 rendered-loudness QC remains unexposed.
• The server is a thin wrapper over the products' public APIs; conformance logic lives in the products, behind their own test gates.
